Description

Technical Field

[0001] This utility model belongs to the field of digital tube testing technology, and in particular relates to an LED digital tube testing device. Background Technology

[0002] LED digital tubes use light-emitting diodes as the light-emitting unit, and offer colors such as single red, yellow, blue, green, white, and yellow-green. Single-color and segmented full-color tubes can be used for lighting the outlines of buildings, roads, and riverbanks. LED digital tubes can be evenly arranged to form large display areas, displaying patterns and text, and playing video files of various formats.

[0003] Existing digital tubes are usually tested one by one using a testing device. During testing, the pins of the digital tube need to be inserted into the testing device for testing, and then the digital tube is taken out after testing. The whole process requires manual operation, and it is inconvenient to replace the pins when encountering larger or smaller pins in the existing slot-type testing device. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an LED digital tube testing device that can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an LED digital tube testing device, including: a base, a support plate located on the base, a movable bracket mounted on the support plate, a cylinder, and a copper sheet mounted on the movable bracket.

[0007] It also includes: a groove is provided on the base, a positive and negative threaded rod is installed in the groove, and a slider is provided on the bottom of the support plate. The support plate is installed in the groove of the base through the slider, allowing the support plate to move along the direction of the groove on the base;

[0008] A set of baffles is fixed on one side of the support plate. The baffles have waist-shaped slots. One side of the cylinder is connected to the waist-shaped slots, allowing the cylinder to move along the direction of the waist-shaped slots on the support plate.

[0009] The movable bracket is mounted on the support plate. The top of the movable bracket has an inclined surface, and a groove is provided below the inclined surface to allow the installation of copper sheets. A connecting plate is also fixed on the side of the movable bracket away from the inclined surface.

[0010] Furthermore, the slider fixed at the bottom of the support plate has a threaded hole inside that matches the thread on the positive and negative threaded rod, and the support plate is installed on the positive and negative threaded rod by threaded connection.

[0011] Furthermore, the cylinder has a threaded hole on the side of the baffle plate near the support plate, and the baffle plate is threadedly connected to the cylinder by a positioning bolt, thus fixing the cylinder to the support plate.

[0012] Furthermore, the cylinder is equipped with a piston rod with internal threads. The connecting plate of the movable bracket, which is fixed near the cylinder, has a through hole that mates with the piston rod. The piston rod is fixed to the connecting plate of the movable bracket by another set of positioning bolts.

[0013] Furthermore, two sets of brackets are fixed on both sides of the base, and each set of brackets is equipped with a set of synchronous pulleys. The two sets of synchronous pulleys are connected by a synchronous belt. The motor is installed on one side of one set of synchronous pulleys, and the drive end of the motor is connected to the internal shaft of the synchronous pulley.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a set of positive and negative threaded rods installed inside the groove on the base, connected to the threaded holes at the bottom of the support plate. By simply rotating a handle fixed to one side of the threaded rods, the distance between the two sets of support plates can be adjusted according to the size of the digital tube to be tested. This effectively solves the problem of traditional testing devices being difficult to adjust when testing different models of digital tubes. Furthermore, a cylinder installed on a baffle on one side of the support plate, with a piston rod connected to a movable bracket, pushes the movable bracket. Due to the inclined design of the movable bracket, the digital tube being transported on the synchronous belt is lifted, and a copper plate installed on the movable bracket performs a contact and energization test on the pins at the bottom of the digital tube. This effectively reduces the number of manual operation steps. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-3 As shown, this utility model is an LED digital tube testing device, including: a base 1, a support plate 2 located on the base 1, a movable bracket 3 and a cylinder 4 installed on the support plate 2, and a copper sheet 5 installed on the movable bracket 3; it also includes: a set of grooves opened on the base 1, with two sides of the positive and negative threaded rods 6 respectively installed on the inner wall of the grooves opened on the base 1, and a handle 13 installed on the outer side of the base 1 through one side of the positive and negative threaded rods 6, and a slider fixed at the bottom of the support plate 2, with a threaded hole on the slider that matches the thread on the positive and negative threaded rods 6, and the support plate 2 is installed on the positive and negative threaded rods 6 by threaded connection, and the two sets of support plates 2 installed on the positive and negative threaded rods 6 can be moved by simply rotating the handle 13, so that they can move inward or outward at the same time. A set of baffles is fixed on one side of the support plate 2. The baffles have waist-shaped slots. The cylinder 4 is located on the support plate 2. The cylinder 4 has a threaded hole on the side near the baffle. A set of positioning bolts 12 passes through the waist-shaped slots and connects to the threaded holes on the cylinder 4 to fix the position of the cylinder 4. The position of the cylinder 4 on the support plate 2 and the position of the piston rod inside the cylinder 4 can be adjusted by tightening or loosening the positioning bolts 12 in the waist-shaped slots, depending on the model of the product to be processed. The movable bracket 3 is also located on the support plate 2. A connecting plate is fixed on the side of the movable bracket 3 closest to the cylinder 4. The connecting plate has a countersunk hole that mates with the piston rod inside the cylinder 4. The piston rod of the cylinder 4 also has a threaded hole. The piston rod is installed inside the movable bracket 3 by another set of positioning bolts 12. An inclined surface is formed on the side of the movable bracket 3 away from the cylinder 4. A groove for installing the copper sheet 5 is formed below the inclined surface. Another set of grooves is formed on the base 1 for the copper sheet 5 to pass through. When the copper sheet 5 is installed above the movable bracket 3, one extended portion of the copper sheet 5 is connected to the external wiring from the bottom of the other set of grooves in the base 1. It should be noted that all parts connected to or in contact with the copper sheet 5 are made of non-conductive materials.

[0024] Two sets of brackets are fixed on both sides of the base 1, and each set of brackets is equipped with a set of synchronous pulleys 7. The two sets of synchronous pulleys 7 are connected by a synchronous belt 8. A motor 9 is installed on one side of one set of synchronous pulleys 7, and the drive end of the motor 9 is connected to the internal shaft of the synchronous pulley 7. By driving the motor 9, the digital tube 11 to be tested can be transported by the synchronous belt 8. During the test, first, the distance between the two sets of support plates 2 is adjusted by rotating the handle 13 to suit the model of the digital tube 11 being tested. Then, the position of the cylinder 4 on the support plate 2 is adjusted to confirm the clamping distance to avoid damage to the pins. The digital tube 11 is placed on the synchronous belt 8 on one side of the base 1, and then the digital tube 11 is limited by the two sets of limiting plates 10 installed on the base 1. The synchronous pulley 7 on one side is driven by the motor 9 to drive the synchronous belt 8 for transport. The connection between the limiting plate 10 and the base 1 is provided with a waist-shaped slot, which can be tightened or loosened according to the model being tested and the size of the digital tube 11. Bolt 12 is used to adjust the distance between the two sets of limit plates 10 so that the digital tube 11 is in the middle position when it is above the synchronous belt 8, which is convenient for testing. When the digital tube 11 is transported between the two sets of moving brackets 3, the piston rod inside the cylinder 4 pushes one side of the moving bracket 3 to make the inclined surface on the moving bracket 3 contact the two sides of the digital tube 11, lifting the digital tube 11 while using the copper sheet 5 below to clamp the pins at the bottom of the digital tube 11. The digital tube 11 is powered on for testing using an external circuit. After the test is completed, the cylinder 4 is driven to retract the moving bracket 3, and the digital tube 11 falls back onto the synchronous belt 8 and is transported to one side of the equipment.
